SULFUR-BURNER.

Specification of Letters Patent.

Patented Dec. 25, 1908.

Application led May 19, 1908. Serial No. 433,735.

To all whom it 'may concern:

Be it known that I, GEORGE ALFRED STEB- BINS, a citizen of the UnitedStates, residing at Watertown, in the county of Jefferson and State ofNew York, have invented a new and useful Sulfur-Burner,of which thefollowing is a specification.

Tins invention relates to sulfur burners.

The object of the invention is to provide an apparatus of this characterwhich will expeditiously and economically burn or oxidize sulfur fr theproduction of sulfur dioxid and in which a substantially uniformquantity of gas may be produced when the apparatus is in full operation,even during the periods when the apparatus is being charged.

Vith the above and other objects in view as will appear as the nature ofthe invention is better understood, the same consists in the novelconstructio'n and combination of parts of a sulfur burner as will behereinafter fully described and claimed.

vin the accompanying drawings forming a part of this specification, andin which like characters of reference indicate corresponding` parts,Figure 1 is a View in side elevation, partly in section, of a sulfurburner com structed in accordance with the present invention. Fig. 2 isan end elevation looking in the direction of the arrow a iin Fig. 1.Fig. 3 is a similar view looking in the direction of the arrow t, inFig. 1. Fig. 4 is a transverse sectional View, on an enlarged scale,taken on the line 4-4, Fig. 1. Fig. is a longitudinal sectional view, onan enlarged scale, of a portion of the cylinder, taken on line 53m-6,Fig. 4.

The cylinder 1 may be of the usual or any preferred construction, andhas secured to its exterior three tracks 2, one being disposedintermediate the length of the cylinder and the other two adjacent tothe respective ends. These tracks are designed to engage grooved rollers3, of which there are six, and are mounted upon shafts 4;. Each of theshafts carries at its forward end a beveled gear 5, and these gearsengage similar gears (i, one only being shown in Fig. 1, that arecarried by a counter shaft 7 driven from a suitable source of power, notnecessary to be shown.

The ends of the cylinder are closed by outwardly-dished heads S and 9,the first head being at the front or feed end of the machine and thelast-named at the rear or discharge end thereof. .The head 8 carries acylindrical throat 10 which 1s provided with a flange 11 through whichpass bolts 12 secured to the head. The forward end of the throat 10 isprovided with a rabbeted flange 12 that is en gaged by a flange 13carried by a throat piece or mouth 14 and is held assembled therewith bya ring 15 that is bolted to the 'flange 12. This arrangement will permitthe cylinder to rotate freely without imparting any strain whatever tothe mouth 1,11. The mouth is supported by a pedestal 16 that is carriedby a concrete base 17. The outer end of the mouth is closed by a door 18provided with draft openings 19, assages through the same being`controlled y a rotary damper 20, as clearly shown in Fig. 2. The head 9is provided with a series of draft openings 21,'in this instance four,as clearly shown in Fig. 3, and these openings are controlled by blankslides 22 which are clamped at the appropriate adjustment by levers 23that are carried by threaded studs 24 arranged in the head 9. The head 9is provided with a tubular extension 25 that communicates with a chamber26 supported upon a concrete pedestal 27. Connecting with the upper ondof the chamber 26 is a pipe 27 that constitutes +he gas outlet and leadsthe acncraied gas to a point where it is further used iu the process.

On two sides 0f the chamber 26 are arranged guides 2S between which aremounted to slide a series of dampers 29 which are provided l'or thepurpose of supplying additional air to the gas if found necessary.

One o f the features of the invention resides in the novel arrangementof buckets by which the hot molten sulfur is picked up and discharged instreams across the air zone. As shown in l? l, these buckets 3() aresemi-circular in cross section and are held' assembled with the cylinderby rivets or bolts 3l. The buckets are arranged`iu 'two series that arereversely disposed, that is to say, the series of buckets at the frontend of the cylinder pick up the sulfur on their concave sides, whihlthose at the rear pick up sulfur on their convex sides. By thisarrangement the greatest bulk of molten sulfur will be projected throughthe air zone at the point of greatest supply, while the lesser bulk willbe passed through thc zone at the point of least supply. By this meansthe generation of the gas will be materially augmented, its quantityrendered practically uniform when the apparatus is in full operation,even during the' period when the apparatus is being charged and thoroughoxidation Will be assured. ;t

The apparatus as a Whole is simple in construction but will be foundthoroughly eflicient for the nurposes designed and Will in operation prouce sulfur dioXid -in a rapid and even manner.

What is claimed is l. A sulfur burner embodying a rotatable cylinderincluding .oppositely-disposed buckets.

2. A sulfur burner embodying a rotatable cylinder including transverselycurved, oppositely disposed buckets. y

A sulfur burner embodying a rotatable cylinder including tWo series ofsemi-circular buckets, those at the front' ofthe cylinder being designedto ick up the sulfur from their concave sides W `le those at the rear ofthe cylinder pick it up from their convex sides.-

4. A sulfur burner comprising'a rotatable cylinder including oppositelydis osed buckets, and rovided at its front en with a stationary t oat,and a door combined With the throat and embodying a regulable air inlet.

5. A sulfur burner comprising a rotatable cylinder including oppositelydisposed buckets, and provided at its'i'ront and rear ends Withregu ableair inlets. 6. A sulfur'burner comprising a rotatable cylinder includingoppositely disposed buckets', and provided at its front and rear endsWith .air controlling mechanism, a chamber into which the ,rear end ofthe cylinder discharges, and a regulable draft inlet combined with thechamber.

7. A sulfur burner comprising a rotatable cylinder, oppositely disposedbuckets arranged upon the interior thereof, regulable air inlets at thefront and rear ends of the cylinder, a chamber into which the rear endof the cylinder discharges, and aregulable draft inlet and a gas outletcombined with the chamber.

In testimony that l claim the foregoing as my own, I have hereto aHiXedmy signature in the presence of two Witnesses.

GEORGE ALFRED STEBBINS.
